Anisotropic Spectral Manifold Wavelet Descriptor
(© 2021 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2021)In this paper, we present a powerful spectral shape descriptor for shape analysis, named Anisotropic Spectral Manifold Wavelet Descriptor (ASMWD). We proposed a novel manifold harmonic signal processing tool termed Anisotropic ... -
Graph‐Based Wavelet Representation of Multi‐Variate Terrain Data
(Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)Terrain data can be processed from the double perspective of computer graphics and graph theory. We propose a hybrid method that uses geometrical and vertex attribute information to construct a weighted graph reflecting ...
